DOUGH-KNEADING MACHINE.

Application filed September 10, 1927. Serial vNo. 218,681.

This invention relates particularly to an Aapparatus for mechanically kneading or rolling dough. Y Y Y An object of theinvention is to provide Va dough kneading machine consisting of a pressure roller and a fabric covered platen adapted to be advanced relative to the roller, to pass the dough to be kneaded between the roller and the platen.

A further object of the invention consists of providing a pair of rollers arranged in spaced relation and a fabric belt, to carry the dough to be kneaded through and between the rollers, movable` in opposite directions relative thereto and a pre-determined distance on opposite sides thereof..

A still further object of the invention relates to an'apparatus for kneading dough that consists of a surface having a metal roller rotatably mounted in spaced relation thereabove, and a fabricbelt to move between and to carry the dough to be kneaded between the roller and surface, the belt being covered with anV absorbent powder to preventl the adhesion of the dough thereto when kneaded by the roller.

Other objects and advantages will appear as this description progresses. In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but itis to be understood that the invention is not limited to such form, because it may be embodied in other forms, andit is also to be understood that in and by the Vclaims lfollowing the description, it is desired to cover the invention in whatsoeverk form it may beeinbodied. n

In the accompanying one sheet of drawings Irig. lis a plan view of a dough kneading machine constructed in accordance with my invention. v

Fig. 2 is a side elevation of Fig. l.

In detail, the construction illustrated in the drawings comprises av table or frame 1 having a relatively flat horizontal upper surface 2. A drive roller 3 is arranged on a horizontal axis transversely across the table surface 2, said roller 3 having a sidethere of projecting above. the upper face of a mediate portion of the tablev surface. The opposite ends of the roller3 are rotatably journaled in supporting members 4 and 5 the horizontally disposed roller 6 parallelly v relative to the drive roller 3. One end of the roller 3 is provided with a pulley 11 .thereon around which a drive belt 12 passes, said drive belt being` connected to the driving pulley 13 on a driviiigmotor 14.` The motor 14 is connected to a source of electrical energy, and, .in combination with a pair of operating switches, is driven in either a clockwise or contra-clockwise direction, whereby the direction of rotation of the drive roller 3 may be varied atk will. A sprocket wheel 15 is `provided on thee treme outer end of the roller 3, to mesh with a sprocket chain 16. The sprocket chainlGV is held in engagement with the sprocket wheel 15 by a pair of idler sprockets 17 and 18 rotatably mounted on the frame 4 contiguous to the sprocket 15. i

A pair of roller reels 19 and20 are rotatablyjournaled at their opposite ends in the frame members 4 and 5 below the table surface 2. The roller reels V19 vand 20 are provided with sprocketV wheels 2l and 22 thereon around which the sprocket chain 16 passes.

A fabric belt 23', preferably made of canvas, is passed over the upper vsurface of the -table 2, and driveroller 3. vOpposite ends of the canvas beltv 23 pass around guide rollers 24 and 25 arranged at opposite ends of the table surface 2 and each of the respective ends of the canvas 23 are wrapped around the respective reel rollers 19 and 20. n

The reel rollers 19 and 2() are so connected by the sprocket chain to the drive roller 3 that the belt .may be Vvselectively moved, in opposite directions, over the table surface to windrfrom one reel roller to the other, and vice versa.

over vthe table surface relative to the driven and idler compression rollers.

.'Ihebelt has the interstices thereof thoroughly saturated with. flour or some other absorbent material having Van afinity forV The movement of the belt. 23. is always in one direction, or the` other,

the dough to be lrneaded, by preventing the said dough from adhering to the surface of the canvas. The mass of dough to be kneaded is Vlaid on the belt, andthe belt moved toward the rollers to force the dough mass between the rollers and gradually .flatten the said dough out by the time the entire body thereof has passed through the rollers. The operator then takes the sheet of flattened dough and rolls it into a mass, and starts the canvas moving in the opposite direction to pass the dough mass back between the rollers to roll it flat again. The action of continuously passing the dough mass back and forth on the canvas underneath the compression rollers to effect the desired lneading thereof, continues as long as desired.

I have arranged the electrical apparatus that actuates the canvas belt to move a predetermined distance in opposite directions over the table surface and then to come to an absolute stop, thus requiring the oper ator to start the machine for each movement of the canvas belt in either direction. VAlthough I have shown a canvas belt moving over a stationary surface, I do not wish to be limited exclusively to that construction, as it would be clearly within the scope of the invention to pass a fabric covered platen having the dough mass thereon beneath a compressing` roller.

Having thus described this invention, what I claim and desire to secure by Let ters Patent is;

1. In combination a pair of rollers arranged in spaced parallel alignment; means to adjust the rollers toward or from each other, a fabric belt to carry `dough to be lnieaded between the rollers, and means en gaging the opposite ends of the belt for reciprocating thebelt between the rollers. Y

2. In combination a Ypair of rollers arranged in spaced parallel alignment; means to adjust the rollers toward or from each other; a fabric Vbelt to carry dough to be lmeaded between the rollers; and means for synchronously driving one of the rollers and alternately reeling the opposite ends of the fabric belt, thereby reciprocating the belt between the rollers.

3. In combination a frame having a flat upper surface; a pair of rollers arranged transversely across said fra-me surface in adjusted parallel relation midway between the ends thereof; a fabric belt movable lengthwise over the table surface to carry dough to be lrneaded between the rollers; and means to synchronously drive one of the rollers and alternately reel the opposite ends of the fabric beltj r et. In combination a frame having a flat upper surface; a pair of rollers arranged transversely across said frame surface in adjusted parallel relation midway between the ends thereof; a fabricbelt movable length wise over the table surface to carry dough to be kneaded between the rollers; and means to'alternately reel the opposite ends of the belt so as to move the beltin alternate opposite directions, over the table surface, relative to the rollers.

5. In combination a frame having a flat upper surface; a roller arranged in spaced relation above the level of said surface; and a fabric belt reciprocable between the frame surface and roller to repeatedly carry dough to be kneaded through and between the roller and surface, and means to alternately reel the opposite ends of said fabric belt so tomove the belt in opposite directions a predetermined distance on opposite sides of the roller.

6. An apparatus for kneading dough comprised of a surface having a metal cylinder rotatably mounted in spaced relation thereabove, a fabric belt, and means to alternately reel the opposite ends of said belt so as to reciprocatethe same between and to repeatedly carry the dough to be kneaded between the cylinder and surface, said belt being covered with an absorbent to prevent the adhesion of the dough thereto when lrneaded by the roller.

7. An apparatus for lrneading dough comprised of a frame; a pair of rollers arranged transversely across the frame in adjusted vparallel relation; a fabric belt movable between the rollers for carrying dough thereon; reels forV reeling the opposite ends of the belt; and reversible means to change the direction of rotation of said reels, thereby reciprocating said belt between said rollers.
